Intelligent Distributed Storage Service System and Method

Abstract

Disclosed is an intelligent distributed storage service system comprising: a web server configured to receive selection information including a virtual storage capacity necessary for a virtual storage service, the number of storage nodes, storage node types, and a distribution method from the terminal when the terminal requests the virtual storage service; at least one storage node configured to generate a virtual disk volume according to external control; a control center server configured to monitor available capacities and usage states of the storage nodes, determine a storage node corresponding to the selection information among the monitored storage nodes, and control the determined storage node to generate the virtual disk volume; and a database (DB) configured to store information of the storage node and virtual disk volume information of the user.

Description

TECHNICAL FIELD[0001]The present invention relates to a control computing technology, and more particularly, to an intelligent distributed storage service system and method.BACKGROUND ART[0002]As control computing is generally raised as an issue, a distributed file system on which control computing is based is under active research.[0003]Most distributed file systems are widely used due to their advantages that it is easy to share information among users and it is possible to efficiently use a storage space while reducing spatial limitations.[0004]Such a distributed file system has characteristics as described below.[0005]Most large-capacity file systems used in existing control environments are directory-based file systems.[0006]Regardless of the types of local file systems of actual nodes, data is divided into chunks (or blocks) having a designated size in a directory designated among several distributed storage nodes and spread over all nodes in a distributed manner.[0007]Also, t...

AI Technical Summary

Benefits of technology

[0028]Exemplary embodiments of the present invention propose a fundamental solution to the risk of loss and infringement of information stored in device volumes, and make it possible to perform a volume snapshot backup excluding duplicated data according to users by assigning user-specific distribution nodes to device volumes.

[0029]Also, it is possible to measure the degree of imbalance in the amount of disk use according to volumes allocated to users, and reduce overhead by performing rebalancing according to the allocated volumes.

[0030]In addition, even in the case of data having a different standard of specifications of a node storage, etc. than other data, it is possible to calculate a result of addition based on the same standard. Also, by applying weights to respective factors, data to be considered with priority is reflected in the result of addition and can be disposed in an objectively appropriate environment in a distributed manner.

[0031]Further, since data is distributed to storage nodes which use a small amount of resources and processed, it is possible to ensure high performance and high availability by disposing low-specification storage equipment in a distributed manner.

Problems solved by technology

However, since a user (or an administrator) cannot know where personal information and data spread in a distributed manner are stored, such an existing distributed file system has the risk of loss and infringement of stored information.

According to an existing method, during a disk backup of user data, data duplication cannot be avoided.

In order to avoid such data duplication, it is necessary to remove data and download the data onto another disk or a server in a separate method used by a user, which is a complex and inconvenient process.

Also, most distributed file systems perform balancing for resolving an imbalance in the amount of disk use, but it is not possible to measure the degree of imbalance at this time.

Also, rebalancing is performed on all disks so that overhead may occur.

Therefore, the original aim of a distributed file system and storage virtualization, that is, the purpose of ensuring high performance and high availability by disposing low-specification storage equipment in a distributed manner may not be achieved.
